Re-installing the default python in Buster

while installing Python 3.7.7 on Buster - I also removed the Python 2.7 that was installed. Do I need to re-install the 2.7? Hate to find out after reboot that it needs 2.7 to get back into desktop. What's my best option to restore/re-install Python 2.7 Here is what I have now: pi@RPi3B:~ $ uname -a...

Headless install on RPi 3B from Windows 10

I've tried to follow several posts that show installation of Raspbian Lite onto RPi 3B without success. Downloaded: BalenaEtcher, SDFormatter, Win32DiskImager, Putty, Raspian Lite (2018-03-13-raspbian-stretch-lite.zip), and the full version (2019-09-25-rpd-x86-buster.iso). I have SanDisk64Gb MicroSD...

Re: How to get the actual date/time of temp data

Thank you Bensimmo. Any idea what the hex data represent? If I understand your suggestion - that requires getting the data directly from the sensor? Most examples I see use the "reading of the file" from /sys/bus/w1/devices/28-0116278c36ee/w1_slave method to get the temperature and time fr...

How to get the actual date/time of temp data

I'm just getting into the world of RPi. When looking at the contents of W1_slave file of a temperature sensor, the following is displayed: 0b 01 4b 46 7f ff 05 10 a8 : crc=a8 YES 0b 01 4b 46 7f ff 05 10 a8 t=16687 What is the data in the hex? 0b 01 4b 46 7f ff 05 10 a8 And most examples I see which ...

Re: Google spreadsheet temperature logger using a DS18B20

Excellent thread. In the contents of the w1_slave what is the leading data on the line? # cat 28-0000066e6162/w1_slave 26 01 4b 46 7f ff 0a 10 64 : crc=64 YES 26 01 4b 46 7f ff 0a 10 64 t=18375 i.e 26 01 4b 46 7f ff 0a 10 64 The reason I ask is to determine what is the date/time the temp was actuall...
